Well, since no project is ever really finished...
The tilt column that came in the car when I bought it, (it was a non-tilt car originally) has been making noises like a bell ringing whenever I'd take the car out for a drive (I have about 700 miles on it now). So I went on the hunt for a non-tilt column and actually found one on ebay. It was listed as a Camaro column but they are the same from 70 to around 76.
The 70-76 columns have a splined end while the 77-81 columns have a D-shaped end that interlocks with a similar intermediate shaft.
I disassembled the column and soaked the steel end in the safestrustremover liquid along with my trusty aquarium heater and pool sump pump and let it circulate or a few hours.
